Short bio: 

Dr. James (J.T.) Eckner graduated from Case Western Reserve University’s School of Medicine in 2003 and completed his residency training in PM&R at the University of Michigan in 2007.  He earned a Master of Science degree in 2009 from the University of Michigan in Clinical Research Design and Statistical Analysis.   He is currently an Assistant Professor in the Department of PM&R at the University of Michigan and is the Director of Clinical Research at Michigan NeuroSport.  He works with the sports medicine programs at the University of Michigan, Eastern Michigan University, and the USA Hockey National Team Development Program.  Dr. Eckner also treats local and regional athletes with concussion seeking care through the Michigan NeuroSport clinic.  

Research summary: 

Dr. Eckner's primary area of research interest is mild traumatic brain injury in athletes, or sport related concussion.  His sport concussion research addresses concussion assessment using a simple clinical test of reaction time; the neck’s role in concussion susceptibility and the potential role for neck strengthening as an intervention to reduce an athlete’s concussion risk; concussion biomechanics using body-worn impact sensors; and assessment of the short- and long-term effects of concussion and sport-associated head trauma on an athlete’s neurocognitive health.
